I´m using an authorised student-version of SolidWorks 2016. I´ve installed it in Nov.2016 and it has always worked fast and satisfying even with mid-sized assemblies.
Since 1 week SolidWorks became really slow. Drawing a line in an simple element needs 3-4 seconds to appear on the screen, rotating an element needs even longer... this makes the work with solidworks really annoying.
SolidWorks is the only programme on my computer which is working that slowly, every other programme or game works without any issues.
Maybe someone can help me !
